The present disclosure relates to the field of artificial honeycombs, in particular to an artificial nest for solitary bees and an application method of the artificial nest. The artificial nest comprises a main enclosure tube, hanging rings, a plurality of trapping hollow tubes and tightening mechanisms used for clamping the trapping hollow tubes. The hanging rings are arranged at an outer sidewall of the main enclosure tube. The tightening mechanisms are annularly arranged at an inner sidewall of the main enclosure tube, and the trapping hollow tubes are fixed in a ring of each tightening mechanism in an axis direction of the main enclosure tube. Each tightening mechanism comprises a connecting steel wire and fastening springs. The sidewall of the main enclosure tube is provided with fixing holes for fixing the tightening mechanisms.

Artificial nest for solitary bees and application method thereof

A transformer bushing partial discharge monitoring chip device and method are provided. An acquisition unit comprises three sensor modules installed at end screens of three-phase bushings of a transformer respectively for acquiring partial discharge signals and power frequency current signals from the transformer bushing end screens; each of the sensor modules is connected to an SIP digitization unit through a wire; the SIP digitization unit is fixedly installed beneath a base of the acquisition unit for digitizing the partial discharge signals and the power frequency current signals; an output end of the SIP digitization unit is connected to an input end of a background processing terminal.
